Hi All. Please help with some advice. We have a Victorian semi which is now driving us mad. The main issues are around damp which appears to be penetrating our bedroom wall. I have only recently redocorated the bedroom which was showing small signs of damp but these are now alarmingly obvious with new paint. I have photos which illustrate how damp the brickwork is after rain on the exterior. The brickwork only appears damp in cetain areas and this is centered around the dormer window. The bricks are sodden at times. We are getting extremely frustrated as we have put money into small roof repairs ( flashing etc ) and nobody can tell us if it is roof or brick related. There is no felt beneath the roof tiles and the roof is itself old. The wall is possibly in need of pointing and has lime mortar. The wall was also treated with cavity filling 18 months ago. Someone please advise me if this could be rain water running from the roof/ dormer valleysp enetrating pointing work and down the brickwork or rainwater leaking through the roof tiles and somehow entering the cavity. As you can see the interior shots show a number of interior patches. These appears much more pronounced in freezing weather. Any help and advice will be gratefully recieved.

Sound to me like the roof and/or dormer that.s your problem. As you say the wall has a cavity it is unlikely that there is bridging between the outer and inner leafs, although not impossible.
I would say your roof needs attention. Probably a strip and re roof with new breathable membrane. If you have had new flashing etc to the dormer i would say this eliminates that as the problem. Truth is, it could be a number of things and could be a case of trial and error with smaller jobs to try and fix the problem, which results in you having a strip and re roof anyway.
I'll give you a couple of examples of what i have seen in the past.
1) ridge tiles need re-pointing, water ingress at the ridge whih is running down the rafters and dripping onto exterior wall around the wall plate.
2) guttering filled with moss etc, water spilling back on top of soffit, water running back towards the house.
3) damp could be from cold bridging and internal moisture is condensing on the cold surface. (doesn't sound like this)
hope this helps
